Dialysis Water Supply Faucet as Reservoir for Carbapenemase-Producing Pseudomonas aeruginosa

Abstract

During June 2017-November 2019, a total of 36 patients with carbapenem-resistant Pseudomonas aeruginosa harboring Verona-integron-encoded metalloβ-lactamase were identified in a city in western Texas, USA. A faucet contaminated with the organism, identified through environmental sampling, in a specialty care room was the likely source for infection in a subset of patients.
